ACS command authorization report in conf t mode

Hi, this is probably a quick one, but I couldnt find a solution so far.
We are using command authorization via ACS and are thus able to see (in case of any issues) who has entered which commands at which time on which device. But this only works until someone enters conf t mode. After that I am not getting log entries in the ACS (Version 5). I can see all show commands and who entered the configuration mode, but nothing after that. Config snippet:
aaa new-model
aaa authentication attempts login 5
aaa authentication login default group tacacs+ local line enable
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ local
aaa authorization commands 1 default group tacacs+ local
aaa authorization commands 15 default group tacacs+ local
aaa accounting exec default start-stop group tacacs+
aaa accounting commands 1 default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+
aaa session-id common
My guess is that I allow all commands with that and thus no authorization is needed.
Any idea?
Thanks
Chris

Cisco ACS command authorization sets

I need help on the following please.
1. - I am using ACS as TACACS server to control IOS authorization on all our Switches, However I can not deny telnet sessions to other devices from within CatOS - does anyone know the command authorization set to deny this within ACS ????
2. Does anyone know where I can read up on command authorizations sets for ACS ??
3. What is the debug command for CatOS to see cli output ?
Many thanks
Rod

Thanks for your info. I have solved my problem -
1. I enabled tacacs administration logging using command on switch aaa authorization commands 15 default group tacacs+
This let me see what what happening everytime I entered a command on CatOS - via the logging monitor on ACS. From here i was able to see that when i was trying to telnet to a device from CatOS it was doing it on Privilage mode 1. I then entered this command aaa authorization commands 1 default group tacacs+ which solved my telnet problem.
Problem resolved.
Many thanks.

ACS command authorization - deny CatOS "set" commands

Cisco Secure ACS 4.2
I have a network support group that i just want to deny them the ability to use IOS and CatOS configuration commands.
I noticed that the Per Group Command Authorization is applicable to only IOS-based commands. I applied it to deny "configure", but permit everything else.
How do I go about setting this group up to deny set-based commands for the CatOS devices?

Hi
CatOS does TACACS+ right? Pretty sure it does. If it has a "shell/exec" service like IOS then ACS wont really care whether the command authorisation is IOS or CatOS - it doesnt have any specific command set knowledge. ie it uses string comparisons between what the device is requesting and what is permitted.
However, if the command authorisations are totally different (between IOS and catos devices) you might need to place them into separate NDGs so that you can map an IOS NDG to an IOS device command set and vice versa.
Hope that makes sense!

Problem - acs command authorization and web access control

Hi, I'm trying to add the control of some aironet 1310 bridges with a ACS 3.2 (tacacs+). I wanted to be able to do telnet command authorization restrictions trough shell command authorization sets and be able to give similar restrictive web access at the same time. I have it working if I permit some commands that are sent by the browser as "write memory quiet" and few other ones, but for it to work, I must give them limited users the privilege level 15 and by having the tacacs server authorizing the commands, it work for both, http and telnet. Where my problem begin is when I loose the connection with the ACS server, the user being already authenticated as level 15 user, the device become open to all commands; there is no more restriction applied by the ACS. Do anybody now a workaround.

It is already at local, that is just that the user already have a level 15 access and I used to control the commands through level settings before. So when I try it, my user that is localy level 5 is already recognized as a level 15 user from when it was authenticated through the ACS. If I could find a way to give web access to the 1310 at priv level 5 and still controlling the command set, it would be ok but as soon as I try to access a page that is not permitted other way than by the view level (i think it's level 1... or 0), I get a username password prompt with that line on the top of it:"level_15_or_view_access" and the only way I can access it is by entering a level 15 un/pass. I attached my 1310 aaa config
and here are the command set that work at level 15 to do a "shut" or "no shut" of the radio interface by the web interface:
configure
permit terminal
exit
permit Unmatched Args
interface
permit Dot11Radio0
no
permit shutdown
permit cca
ping
permit Unmatched Args
show
permit Unmatched Args
shutdown
permit Unmatched Args
telnet
permit Unmatched Args
write
permit memory quiet
Thanks for the help !

Nexus 5500 - unexplainable mutual-exclusion error when using "conf sync" mode

We have 2 Nexus 5548UP switches which are running NX-OS 7.0(5)N1(1).
I'm trying to reconfigure an interface, which was previously configured in conf t (local) mode on both switches, in conf sync mode.
Original config:
conf t:
interface Ethernet104/1/33
inherit port-profile DevServers
I've changed the configuration so that the vlan was manually configured and the port-profile was removed from the interface. Otherwise, it was not possible to configure a Port-profile inheritance in conf sync mode (as this was in conflict with the config in local mode).
Current config:
conf t:
interface Ethernet104/1/33
switchport access vlan 13
However, when I try to configure a PP inheritance for this interface in conf sync mode, I'm getting the same error as if there were a conflict:
conf sync:
interface Ethernet104/1/33
inherit port-profile DevServers
commit
Failed: Verify Failed
Status: Verify Failure
Error(s):
Following commands failed mutual-exclusion checks:
interface Ethernet104/1/33
inherit port-profile DevServers
When I configure another interface (not in use) with exactly the same configuration (so access vlan 13 in conft mode on both switches, and then a PP inheritance in conf sync mode), it is accepted and the configuration is correct. It looks like something is stuck within the NX-OS switch which makes it believe that the PP inheritance is still configured in conf t mode...
I've had this issue before on another interface, and found somewhere on the internet that the NX-OS keeps an internal database, which is mysteriously not always in sync with the current running-config, and that this could be forece manually with the command "resync-database" in conf-sync mode. On that other interface, this resolved the issue, but this time, it does not work and I keep getting the above error when I want to configure the port-profile.
Any suggestions?

Ok... I found the source of the problem (looks to be buggy behaviour).
Here's my recent blog post that covers a detailed description and a fix/workaround:
http://nexp.com.ua/technologies/nx-os/troubleshooting-nx-os-config-sync/
Hope this will help anyone.

ACS - Shell Command Authorization Sets

Hi,
I have had a problem where a set of users in two groups in ACS are struggling entering commands. The commands are set in the Shell Command Authorization Sets and this hasnt changed. Other commands are working. As this is spanning two groups in ACS I am thinking it's not something with the groups but the command sets itself.
Just to check, the commands are 'clear port-security' and clear mac address-table' - I have entered in Command 'clear' and the following attributes;
permit port-security
permit mac address-table'
I've also ticked 'Permit unmatched args'
At the same time as this is occuring I have been recieving the following messages from the ACS server via email;
Test Timed out for service: CSAdmin
Test Timed out for service: CSAuth
Test Timed out for service: CSDbSync
Test Timed out for service: CSLog
I have looked at other posts and have restarted CSMon. This then stops the messages for some time, then a day or so later I get the messages again.
Could this be tied in with the command issue? Is there something else I should look at other than restarting the server and the CSMon service again? All other CS' services are running.
Thanks!!
Steve

Thanks for your reply!
there are no errors, the switch ios is putting the asterics as it does when you enter a command that is not recognised, i.e. for clear port-security the port-security onwards is not recognised. On this note, the user is entered into priviledge mode and not in configure terminal mode, just base priviledge mode. The group in ACS is set to max priviledge level 7 and have also set this on the user account in addition.
I am using ACS v 4.1.
While I receive the service messages and also when they go away - I always have the authorisation problem.
Thanks
Steve

ACS 3.3 Config Command Authorization

Hi,
I want to allow an user only to add/remove routes on a router. The shell command authorization works fine. But when the user is in config mode, he can start any command!
The debug says:
1w2d: AAA/AUTHOR: config command authorization not enabled
How can I enable this and how/where can I configure it on the ACS?
Thanks in advance

On ACs just allow the user to enter the "route" command like you have any other shell command they're allowed to do.
On the router/NAS, you have to tell it specifically that you want authorization for config commands with the following:
aaa authorization config-commands
Note that the format of this command changes slightly on different IOS versions, but if you do "aaa authorization ?" you'll be able to figure it out.

Hi Jatin ,
first of all Thank you very much . It startted working after aaa authorization config-commands
here I was trying to achive one specfic thing .
I want to stop the following commands on ACS “switchport trunk allowed vlan 103” . I only want allow “add” after “vlan” and block rest all arguments
But even after setting the filter on ACS Still we are able to execute the command is there anything like we cannot control the commands after the sub commands
Also I am attaching the filter list along with this. Could you have look on this and let me know whether I have configured something wrongly. Other than this is there any work around is available to achieve this .
Thanks and Regards

ACS Shell Command Authorizations Set

I have Cisco ACS Server V4.0
In the shell Command Authorization Set I configure a restrict Access.
In the privilege mode the restriction of the commands works good, but when I enter in the config prompt the restriction don't works. In this promt I can enter all commands.
Why This?

I have the same error with ACS Server 4.2. I can restrict in privilege mode but global config is wide open. Also any command i block in privilege mode can still be executed in global config using the "do" command. How do i block that, or find out what commands the router is sending to the ACS.

ACS 5.3 Showing Clear Text Password in Authorization reports

Hello,
When a tacacs user is changing the local password on the router (for local user), the acs 5.3 is showing the new password in clear text in authorization reports/logs.
This behaviour is seen on acs 5.x, whereas acs 4.2 is showing encrypted password in the reports.
I have checked debugs on Router and it is sending password in clear text in Tacacs Authorization packet but encrypted password in Tacacs Accounting logs.

Thanks Tarik,
But it seems it did not help overall
Akhtar: Cisco needs long time to fix bugs unless it is P1 or P2 bug. Otherwise they'll do it at their leisure.
If you are not on latest patch already then upgrade. If you are already on the latest patch then wait for the next one. If your bug is not mentioned to be fixed on the resolved caveats don't panic. I've seen many bugs fixed but not mentioned in the release notes. What you need to do is to contact TAC so they contact the BU for your behalf to confirm if the bug is resolved or not.

Cisco Secure ACS 4.2 - Group Setup w/Shell Command Authorization Sets

Hello All,
I am trying to create a user so that I can provide him only to run commands that I have designated them to run within my "Shell Command Authorization Set". This seems to work great, however I cannot find anywhere I can "hide" commands they do not have access to. For instance, once the user is logged into the switch they can do a show ? and get a list of commands. I would like to know if there is an option to only display commands the user has access to in ACS.
My Steps:
Created a user in ACS
Shared Profile Components
Create Shell command Autorization Set - "ReadOnly"
Unmatched Commands - Deny
Unchecked - Permit Unmatched Arg
Commands Added
permit interface
permit vlan
permit snmp contact
permit power inline
permit version
permit switch
permit controllers utilization
permit env all
permit snmp location
permit ip http server status
permit logging
Created a group - "GroupTest" with the following
Confirgured - Network Access Restrictions (NAR)
Max Sessions - Unlimited
Enable Options - No Enable Privilege
TACACS+ Settings
Shell (exec)
Priviledge level is check with 1 as the assigned level
Shell Command Authorization Set
"ReadOnly" - Assign a Shell Command Authorization Set for any network device
I have configured following on my Router/Switch
aaa authorization config-commands
aaa authorization commands 1 default group tacacs+ if-authenticated
privilege exec level 1 show log
I have attached below the documention I have gone over.
http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_configuration_example09186a00808d9138.shtml
http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2/user/guide/GrpMgt.html#wp478624

"you are testing with privilege level 15 or below 15. Because when you are using below 15 level user, first it will check local command authorization set. For example if you want to execute sh runn command with level 5 user, first it will check local command set. If the sh runn command exits in local command set then it will send request to ACS. If it is not in the command set, it won't send request to ACS. That's why you don't see debug. For 15 level users it will directly send request to ACS. Configure command set locally and try it should work.
Correct me if I am wrong."

Command Authorization Config best practice using ACS

Hi
Is there any best practices for configuring Command authorization (for router/switch/asa) in CS-ACS? To be specific, is there any best practices to configure authorization for a set of commands allowed for L1,L2,L3 support levels?
Regards
V Vinodh.

Vinodh,
The main thing here is to ensure that we have backup/fall-back method configured for command authorization, inorder to avoid lockout situation or do wr mem once you are sure configs are working fine.
Please check this link,

permit vlan
With the above configuration iam still able to add a route to the config
Also i would like to know the wildcard to be used for enabling all the fastethernet or Ge ports

Command Authorization in ACS 5.0

Hi,
Can anybody route me to configuration example for command authorization in routers or switches or firewall for ACS 5.0.
OR
USER-A should be placed in privilege level 2 and given access to all debug commands and the undebug all command.
Assigned specified commands to level 2
privilege exec level 2 undebug all
privilege exec all level 2 debug
The commands what i applied on routers are above.How i can set a privilege level of 2 on user in ACS 5.0.??????
Also if i want to do shell command authorization set,how can i do it in ACS 5.0
Thanks,

You need to create a shell profile to assign the desired privilege level, and a command set to authorize specific commands, then associate those two with the authorization policy that applies to those users.
